Abstract

Disclosed herein is a new variety of Senecio plant having a semi-dwarf, obconical shape with abundant branching and small leaves. The capitula are single and small, the ray florets have a vivid violet color and the disc floret color is brilliant violet. The blooming time is early and flowering duration is longer than Senecio cruentus. ‘Sunsenebabu’ has low fertility.

Description

Botanical classification: Senecio cruentus×Senecio heritieri.
Varietal denomination: ‘Sunsenebabu’.
BACKGROUND OF THE VARIETY
The present invention relates to a new variety of Senecio plant, which originated from the crossing of the cultivar ‘Extra Blue’ (unpatented) as the female parent with a variety of Senecio heritieri as the male parent.
There are many varieties in Senecio L. and Senecio cruentus, well known as Senecio, cultivated in the world. There are many cultivated varieties with capitula of a single color of white, pink red, blue or violet. Some varieties have marginal variegation with off color parts.
The female parent ‘Extra Blue’ used in the crossing that produced ‘Sunsenebabu’ is a cultivar of Senecio cruentus. It is early flowering variety having dwarf and mounding shape with large leaves. It has small single capitula, the ray florets having a vivid purple color. The seed of ‘Extra Blue’ is commercially available.
The male parent Senecio heritieri used in the crossing that produced ‘Sunsenebabu’ is a cultivar having a high and dome-shaped growth habit with abundant branching and small leaves. It has small single capitula, the ray florets having strong purple with vague white center coloration. Senecio heritieri, introduced from nurseries in England, has no variety name and, to Applicant's knowledge, is neither patented nor sold in the United States.
In January 1996, crossing of ‘Extra Blue’ as the female parent and Senecio heritieri as the male parent was conducted at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan. The seedlings obtained from that crossing were grown in pots in glasshouses and evaluated from July 1996. One seedling was selected in view of its growth habit, flower color and flowering time in December 1996. That seedling was propagated by cutting and grown in pots. A trial was carred out in pots from July 1999, at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan. The botanical characteristics of that plant were then examined, using similar varieties ‘Sunsenebu’ (U.S. Plant Pat. No. 12,104) and ‘Miss Yokohama’ (unpatented) for comparison. As a result, it was concluded that this Senecio plant is distinguishable from any other variety, whose existence is known to us, and is uniform and stable in its characteristics. The new variety of Senecio plant was named ‘Sunsenebabu’.
The new variety was first asexually reproduced by cuttings in Hakushu-cho, Kitakoma-gun, Jamanashi, Japan.
In the following description, the color-coding is in accordance with The Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S.).
SUMMARY OF THE VARIETY
This new variety is unlike any Senecio commercially available known to the inventor as evidenced by the following unique combinations of characteristics.
    • 1. Semi-dwarf, obconical plant shape having abundant branching with small leaves.
    • 2. The capitula are single and small. The ray floret color is vivid violet (near R.H.S. 94A). The disc floret color is brilliant violet (near R.H.S. 68D).
    • 3. Blooming time is early, and flowering duration is long.
    • 4. Low fertility.
The new variety ‘Sunsenebabu’ differs from the similar variety ‘Sunsenebu’ in the following points.
    • 1. The plant size of ‘Sunsenebabu’ is smaller than that of ‘Sunsenebu’.
    • 2. The capitulum diameter of ‘Sunsenebabu’ is smaller than that of ‘Sunsenebu’.
    • 3. The disc floret color of ‘Sunsenebabu’ is brilliant violet (near R.H.S. 89D), while that of ‘Sunsenebu’ is deep violet (near R.H.S. 93A).
    • 4. The peduncle length of ‘Sunsenebabu’ is shorter than that of ‘Sunsenebu’.
    • 5. The blooming time of ‘Sunsenebabu’ is earlier than that of ‘Sunsenebu’.
The new variety ‘Sunsenebabu’ differs from the similar variety ‘Miss Yokohama’ in the following points.
    • 1. The plant height of ‘Sunsenebabu’ is higher than that of ‘Miss Yokohama’.
    • 2. The number of the branches of ‘Sunsenebabu’ is more than that of ‘Miss Yokohama’.
    • 3. The leaf of ‘Sunsenebabu’ is smaller than that of ‘Miss Yokohama’.
    • 4. The disc floret color of ‘Sunsenebabu’ is brilliant violet (near R.H.S. 89D) while that of ‘Miss Yokohama’ is vivid violet (near R.H.S. 96A).
    • 5. The blooming time of ‘Sunsenebabu’ is earlier than that of ‘Miss Yokohama’.
    • 6. The flowering duration of ‘Sunsenebabu’ is longer than that of ‘Miss Yokohama’.
This new variety of Senecio Plant ‘Sunsenebabu’ was asexually reproduced by the use of cuttings at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan, and homogeneity and stability thereof were confirmed. The instant plant retains its distinctive characteristics and reproduces true to type in successive generations.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The depicted plants had been reproduced by the use of cuttings and were photographed during January 2003 while growing outdoors in 12 cm pots at an age of approximately 5 months at Yokaichi-shi, Shiga-ken, Japan.
FIG. 1 illustrates a typical plant of the new variety of Senecio plant ‘Sunsenebabu’ growing in a pot.
FIG. 2 illustrates a close-up view of typical capitula of the new variety of Senecio plant ‘Sunsenebabu’.
